Abstract
The invention provides a method for prolonging a video storage time of a video monitoring system. The method comprises the following steps: (1) setting a threshold of an occupancy rate of a storage system, and starting processing when the occupancy rate of the storage system exceeds the set threshold; (2) selecting a to-be-processed video file; (3) performing intelligent video processing on the selected video file, and verifying whether the current scene is a long-time static scene or a quick moving scene, wherein all video frames are discarded in the long-time static scene until a moving scene element comes; all video frames are stored in the quick moving scene to ensure the video quality; video key frames are stored in other scenes; and (4) decoding and re-encoding the intelligently analyzed data, and storing the encoded video file in the storage system. According to the method provided by the invention, balance is achieved between the video recording quality and the prolonging of the storage time, the resolution of the video is not reduced, the key information is not lost in the moving scene, and the video compression ratio can be greatly improved in the static scene.
Description
Technical field
The invention belongs to method for processing video frequency field, is related to a kind of side for extending video monitoring system video recording storage time
Method.
Background technology
In field of video monitoring, because by hardware storage device capacity limit or cost control, when storage system is filled with record
During picture, can only select to delete date video file at most or abandon date newest video file.User is generally to depositing
Storage longer time video monitoring equipment has strong expectation, while and being not intended to this and paying great number System Expansion cost.It is stored in
The video recording of storage system to the value of user be it is distinguishing, date more long video recording comparatively to user's use value more
It is low.
Patent CN105872552A：Extend the intelligent processing method of video monitoring system video recording storage time, by day
The scheme that phase, video file was effectively treated to extend monitoring system video recording storage time at most, realizes system video recording storage
The prolongation of time.But its scheme relies on key frame of video and extracts, and there is certain drawback, and one is, if video is quick sports ground
Under scape, meeting lost part video details reduce video recording value.Two are, for long-time still frame scene, save many weights
Multiple key frame, reduces storage system utilization rate.
The content of the invention
The present invention is in order to make up the deficiencies in the prior art, there is provided one kind can improve video recording value and storage system is utilized
The method of the prolongation video monitoring system video recording storage time of rate.
The present invention is achieved through the following technical solutions：
The method of the prolongation video monitoring system video recording storage time of the present invention, it is characterised in that：Comprise the following steps：
（1）, setting storage system occupancy threshold value, storage system occupancy exceed setting threshold value when unlatching process；
（2）, select pending video file；
（3）, image motion algorithm of target detection is adopted to the video file selected：Image interframe differential method, differentiates current field
Whether scape is long-time static scene or fast motion scenes；Wherein long-time static scene, loses all frame of video, Zhi Daoyou
Moving scene key element is arrived；Fast motion scenes preserve all frame of video, it is ensured that video quality；Other scenes retain Video Key
Frame；
（4）Video file after coding is saved in storage system by the decoding data and re-encoding after intellectual analysis.
Step（3）In, using image motion algorithm of target detection：Image interframe differential method, refers to, if continuous unchanged
Frame number is more than M, is defined as long-time static scene；If continuous unchanged frame is less than N, fast motion scenes are defined as；If
Continuous unchanged frame is less than M simultaneously more than N（N<M）, it is defined as other scenes.
The invention has the beneficial effects as follows, it is simple to operate, easy to use, obtain between video recording quality and memory space extend
Balance, it is ensured that video resolution is not reduced, and key message is not lost under moving scene, greatly can be carried under static scene again
High video recording compression ratio, extends video recording storage time；In the case where monitoring system is without hardware storage device, record is extended
As storage time, System Expansion cost is saved, video monitoring product cost is improve.
Description of the drawings
Fig. 1 is the workflow schematic diagram of the present invention.
Specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.
The present invention is achieved through the following technical solutions：
The method of the prolongation video monitoring system video recording storage time of the present invention, it is characterised in that：Comprise the following steps：
（1）, setting storage system occupancy threshold value, storage system occupancy exceed setting threshold value when unlatching process；
（2）, select pending video file；
（3）, image motion algorithm of target detection is used to the video file selected：Image interframe differential method, differentiates current field
Whether scape is long-time static scene or fast motion scenes；Wherein long-time static scene, loses all frame of video, Zhi Daoyou
Moving scene key element is arrived；Fast motion scenes preserve all frame of video, it is ensured that video quality；Other scenes retain Video Key
Frame；
（4）Video file after coding is saved in storage system by the decoding data and re-encoding after intellectual analysis.
Step（3）In, using image motion algorithm of target detection：Image interframe differential method, if continuous unchanged frame number
More than M, long-time static scene is defined as；If continuous unchanged frame is less than N, fast motion scenes are defined as；If continuous
Unchanged frame is less than M simultaneously more than N（N<M）, it is defined as other scenes.
The method of the prolongation video monitoring system video recording storage time of the present invention, determines the control that processing function is opened and closed
Opportunity processed, that is, the threshold value of storage system occupancy is set, real-time detection storage system occupancy, when system memory resources utilization rate
Reach this threshold triggers function；Pending video file is selected, video file enters at most to date for having been preserved in system
Row is processed, priority treatment date video file at most, it is ensured that the video recording quality of date newest natural law；Record to selecting
As file is with intelligent video process, differentiate whether current scene is long-time static scene or fast motion scenes.It is wherein long
Time static scene, loses all frame of video, until there is moving scene key element to arrive；Fast motion scenes preserve all videos
Frame, it is ensured that video quality；Other scenes retain key frame of video.Decoding data and re-encoding after intellectual analysis, will compile
Video file after code is saved in storage system.With the process of file, storage system occupancy slowly can be reduced, when storage system
System occupancy then closes the processing function less than given threshold, so moves in circles.
